RegistrationCPF

RegistrationCPF is a term used to describe a digital process, module, or API that registers and verifies a Cadastro de Pessoas Físicas (CPF) number within a platform. The CPF is the Brazilian individual taxpayer registry number, issued by the Receita Federal do Brasil, and serves as a unique identifier for residents and some foreign nationals for tax and civil purposes. RegistrationCPF systems aim to establish the validity of a provided CPF, link it to basic identity data, and enable subsequent access to services such as banking, e-commerce, or government portals.

Typical steps include collecting the CPF number, verifying its format and checksum, optionally collecting name and date of birth for corroboration, performing internal or external identity checks, and returning a status (valid, invalid, suspended) along with risk signals. Some implementations require user consent and LGPD/GDPR-compliant data handling, including encryption, access controls, audit logs, and data retention limits.

Key data fields might include cpf_number, full_name, birth_date, address, and timestamps; systems may also record verification_score and source_of_truth. Privacy and security considerations are central, given the sensitive nature of tax identifiers.

Use cases include onboarding for banks and fintechs, loan applications, telecom services, and government service access. Limitations include dependence on data quality of external registries, potential false positives, and regulatory constraints on data sharing.
